Metallica = Haven't made anything good since the 1980s
Trivium = Metalcore = Metallica/Iron Maiden wannabes = Fail
Avenged Sevenfold = Metalcore = Faggots with hilariously bad musicians and a large fanbase of blind retards = Fail
Slipknot = Nu-Metal = Attention whores who have 9 members capable of making music equivalent to a 2 person band and wear masks in an attempt to seem cool and original whilst proclaiming to be as heavy as Grindcore = Fail
Bullet For My Valentine = Metalcore = I don't even have to make fun of them, they do it by themselves with their god awful music and hilariously shitty lyrics = Fail
